Michel Lind 
So ... We talk about how the world should wean itself off fossil fuels and then we won't really be suffering through oil shocks (plus the planet is burning and we can't afford to keep burning fossil fuels anyway!)
But we can go further ... as John Lennon sang in Imagine
Imagine there's no countries
It isn't hard to do
Nothing to kill or die for
And no religion too
Imagine all the people
Living life in peace
